Abstract

The invention relates to the field of wireless communication, and provides an adaptive beam width determination method and system, a base station and a medium. The method comprises the following steps: acquiring the detection probability of the ith time slot and the communication rate of the ith time slot according to the beam alignment probability of the ith time slot; and in a beam width range when the detection probability of the ith time slot is greater than or equal to a preset detection threshold value, taking the beam width when the communication rate of the ith time slot is maximum as the beam width of the ith time slot, or in the beam width range when the communication rate of the ith time slot is greater than or equal to a preset communication threshold value, taking the beam width when the communication rate of the ith time slot is maximum as the beam width of the ith time slot. And taking the beam width when the detection probability of the ith time slot is maximum as the beam width of the ith time slot. By means of the method, the problems that in the prior art, when radar is used for assisting beam alignment, the communication rate is reduced, a radar cannot detect the user equipment, even a wireless communication link cannot be established and the like in a high-speed moving scene of the user equipment can be effectively solved.

Description

technical field [0001] The present application relates to the field of wireless communication, and more particularly, to an adaptive beamwidth determination method, system, base station and medium. Background technique [0002] With the development of wireless communication technology, terahertz frequency band communication has become an important and potential technology. Due to the short wavelengths of terahertz, a large number of antennas can be integrated into smaller devices, reducing the cost of the device. Moreover, the use of terahertz signals can greatly improve the data transmission rate and the resolution of radar sensing. [0003] On the basis of traditional beam alignment through beam training, the existing technology also uses radar-assisted beam alignment, and uses radar to identify the echoes reflected by the user equipment to detect the user's position, so as to perform beam alignment with the user equipment, which can effectively Shorten communication tim...
